Brief Summary
Objective: This prospective interventional study introduces "SeeMe," an automated, high-resolution computer vision platform designed to objectively quantify microscopic, auditory command-evoked movements in patients with Traumatic Brain Injury (TBI). Current clinical assessments, such as the Glasgow Coma Scale (GCS) and Coma Recovery Scale-Revised (CRS-R), rely on subjective human observation and often fail to detect low-amplitude motor responses, potentially misclassifying up to 25% of patients as unresponsive. Methodology: SeeMe utilizes vector analysis, cross-correlation, and deep neural networks (DNNs) to track individual facial pores and hand movements with sub-millimeter precision (0.5 mm) and high temporal resolution (0.03s). The study will enroll a cohort of 60-80 TBI patients, alongside healthy controls and pharmacologically paralyzed subjects, to validate SeeMe's sensitivity and specificity. Primary Goals:
- 1.Validation: Compare SeeMe's detection of voluntary motor recovery against gold-standard clinical examinations (CRS-R).
- 2.Synchronization: Simultaneously record and time-lock electroencephalography (EEG) and electrocorticography (ECoG) with SeeMe-detected movements.
- 3.Biomarker Identification: Characterize neural signatures (specifically Beta-band oscillations) associated with the return of voluntary behavior.

Outcome Measures
Primary Outcomes (1)
Lead Time to Detection of Command-Following by SeeMe Compared With Blinded CRS-R Assessment
Number of days between the first SeeMe-detected significant stimulus-evoked motor response and the first blinded Coma Recovery Scale-Revised (CRS-R) assessment demonstrating command-following. A SeeMe-positive detection is defined as a stimulus-evoked movement that meets the prespecified criteria of a Kolmogorov-Smirnov statistic \>0.1 and a pixel displacement \>400. This stimulus-evoked movement must be detected reliably (at least 3 out of 10 trials). CRS-R examiners will be blinded to SeeMe outputs.
From Day 1 until hospital discharge, typically within 45 days.
Secondary Outcomes (7)
Diagnostic Performance of SeeMe for Subsequent Confirmed Command-Following
From Day 1 until hospital discharge, typically within 45 days.
Rate of SeeMe-Detected Responsiveness in Participants Without Observable Command-Following at Enrollment
From Day 1 until hospital discharge, typically within 45 days.
False Positive Rate of SeeMe in Pharmacologically Paralyzed Controls
During the localized 60-minute window of the surgical anesthesia procedure.
Correlation Between SeeMe Motor Initiation and Beta-Band Event-Related Desynchronization (ERD)
At each synchronized recording session from Day 1 through hospital discharge, typically within 45 days.
Multi-Class Command Classification Performance of the Bidirectional LSTM Model
Assessed at the end of R61 model development and validation, approximately Year 3.

Study Arms (3)
TBI Patients
EXPERIMENTALPatients with Traumatic Brain Injury receiving the SeeMe Auditory Stimulation protocol daily to detect covert motor responses
Healthy Control Cohort
ACTIVE COMPARATORAwake, healthy volunteers receiving the SeeMe protocol to establish "ground truth" for normal voluntary motor signatures and algorithm sensitivity.
Sedated/Paralyzed Patients
SHAM COMPARATORPatients undergoing general anesthesia and pharmacological paralysis receiving the SeeMe protocol to establish the algorithm's specificity and "noise floor."
Interventions
A standardized, computer-controlled auditory stimulation (AS) protocol designed to elicit and quantify microscopic motor responses. Protocol Details: Stimuli: Participants are presented with five distinct auditory commands: 1) 'Stick out your tongue,' 2) 'Open your eyes,' 3) 'Show me a smile,' 4) 'Close your hands,' and 5) a neutral control command ('Today is a sunny day'). Timing: Each command is presented 10 times via single-use headphones with a randomized 30-45 second jittered interval between trials to distinguish stimulus-evoked responses from spontaneous arousal. Data Capture: Responses are captured using high-resolution video (Panasonic HC-2000X) at 0.03s temporal resolution and synchronized millisecond-level EEG/ECoG. Analysis: Displacement heatmaps are generated via facial pore vector analysis and classified using a bidirectional long short-term memory (LSTM) neural network to determine the statistical significance of motor initiation compared to a 15-minute resting base
Eligibility Criteria
You may qualify if:

- No legal authorized representative (LAR) available to provide informed consent for the patients in a comatose state
- Any other medical condition that, in the judgment of the investigator, makes participation in the study unsafe.
- Pregnant women
- Any previous history of traumatic brain injury
- Any neurodegenerative disease such as dementia
- Group 2: Healthy Control Cohort
- Adults 22+ with no history of neurological or psychiatric disorders
- Normal baseline neurological examination
- Intact auditory pathways

Data Sharing
- IPD Sharing
- Will share
- Shared Documents
- STUDY PROTOCOL, SAP, ICF, ANALYTIC CODE
- Time Frame
- Data will be made available beginning 6 months after the primary manuscript is published and will remain accessible for a period of 5 years. This allows the primary research team time to complete secondary analyses while ensuring the data remains useful for the scientific community during the R33 transition phase.
- Access Criteria
- Data will be shared with researchers who provide a methodologically sound proposal and have obtained IRB approval from their home institution. Proposals must be directed to the Principal Investigator (Sima Mofakham). To gain access, data requestors will need to sign a Data Use Agreement (DUA) that strictly prohibits any attempt to re-identify participants or use raw signal data for non-academic purposes.
De-identified individual participant data (IPD) that underlie the results reported in the primary publication will be made available. This includes numerical vector data from SeeMe facial/hand tracking heatmaps, synchronized EEG/ECoG power spectra (Beta, Alpha, Delta, Theta bands), and blinded CRS-R clinical scores. To protect participant privacy, raw high-resolution video files will not be shared; however, processed, anonymized displacement time-series and algorithmic classification outputs will be provided. The Study Protocol and Statistical Analysis Plan will also be available.
